Migration is a complex social phenomenon. It is therefore important to study the Haitian migratory movement to Brazil, which since 2010 has used the territory of Acre as a gateway to the rest of the country. The Haitian migratory flow to Brazil is something new. So let's understand why Haitians chose the illegal route to enter Brazil and why they chose Acre as their route. It is located far from the country's major economic centers. Is it because of the ease of entry at the border? Easy access to documentation for legalization? A route without too many controls? This process began shortly after the earthquake that violently shook Haiti. The catastrophe killed approximately 223,000 people and left 1.5 million people with nowhere to go. The aim of this book is therefore to find explanatory factors for the recent migration of Haitians to Brazil through the state of Acre.
